Compatibility mode: HotRod client sends request to wrong owner -------------------------------------------------------------- Key: ISPN-5981 URL: https://issues.jboss.org/browse/ISPN-5981 Project: Infinispan Issue Type: Bug Components: Remote Protocols Affects Versions: 8.0.1.Final, 8.1.0.Beta1 Reporter: Dan Berindei Assignee: Galder Zamarreño Attachments: GetAllCompatDistTest.java The HotRod client computes the hash on the serialized key, i.e. {{MurmurHash3.hash(obj2bytes(key))}}, but the server decides the entry location based on the unmarshalled key, i.e. {{MurmurHash3.hash(key.hashCode())}}. I've modified {{GetAllCompatDistTest}} (attached) to test if there are any {{ClusteredGetCommand}}s being sent for {{RemoteCache.get(key)}} operations, and it finds quite a few: {noformat} java.lang.AssertionError: expected:<100> but was:<147> at org.testng.AssertJUnit.fail(AssertJUnit.java:59) ~[testng-6.8.8.jar:?] at org.testng.AssertJUnit.failNotEquals(AssertJUnit.java:364) ~[testng-6.8.8.jar:?] at org.testng.AssertJUnit.assertEquals(AssertJUnit.java:80) ~[testng-6.8.8.jar:?] at org.testng.AssertJUnit.assertEquals(AssertJUnit.java:245) ~[testng-6.8.8.jar:?] at org.testng.AssertJUnit.assertEquals(AssertJUnit.java:252) ~[testng-6.8.8.jar:?] at org.infinispan.client.hotrod.GetAllCompatDistTest.testGetWithCompatibility(GetAllCompatDistTest.java:57) ~[test-classes/:?] {noformat}
